You don’t run 7 outside views. You run 3. You can simple try it by deleting 2 of the views and check your framerate in Unlimited mode. 

Then add an extra view and check your franerate again. The same wheh adding your third view.

You will see that your FPS drop 40-50% with each extra view

I have a 4090 , ASUS ROG mobo, 13900F @ 5,3/5.5 GHz , 2Tb M2 and push/pull liquid cooling system.

Here my server runs 2 outside views and I have a Left view client to keep FPS high.
All running in 4K. Almost all settings at Ultra and some at High. PSXT Live Traffic with Lots of AI ac. REX Atmos. DLSS 4. 

It is exoensive to keep on upgrading 2 pc’s so a couple of months ago I tried with 3 views and I lost almost 50% FPS.

I tested with 1, 2 and 3 views and every extra view resulted in almost 50% less FPS.

Here a vid : all in 4K + Map Enhancement Mod (Latest Bing in HD)

 

I run four exterior views and my frames don't drop 50% for each additional view added into the mix.

Then you might use settings that are not that heavy on your system.

And with those 4090s you have an advantage 🥳

According to your specs you are running 5 computers with 3 4090 cards, one 3090 and one 1080ti.

It's not surprising you are not observing the typical fps drop. This is not in any way comparable to running multi monitors on a single pc, whether it has one or 2 graphics cards.

Hi,

During this test I'm running 2K with the settings above ultra with terrain level maxed out at 400 and effects level maxed as well at 200. Only thing turned down are the windshield effects as I don't see them with my setup.

Hi,

I only run multiple computers when running X-Plane 12 via networking. MSFS is not capable of inhouse networking, hence why I run seven monitors via one computer in 2020.

The extra memory I have on the 4090 could be all the difference in performance, it also depends on the CPU in use on his end and where the bottleneck exists.

I've suffered from stutters in the past and it all had to do with certain drivers/settings, DLSS4 makes a big difference in performance when installed correctly.

With my 4070 (not ti nor super) 12 GB: I can run two 1440p 16:9 monitors. But not in TAA nor DLAA. And not in DLSS quality with Ultra preset. In fact the game freezes up every few minutes, completely freezes.

But with DLSS Balanced and rendering High End, it all works perfectly smooth everywhere for flights lasting an hour or longer. Always. My fps locks at 72 and stays there at 72 (2X LS with RLSS locked at 36). Monitor set to 75Hz refresh rate. Amazing the difference reducing settings does. Never an issue. I almost never see the fps go below 69, even in high dense airports.

I use full screen (alt enter) and then LS scaling. It covers the both screens. nvidia surround, native FG off because the newer versions of LS does FG better.

I don't think I could run 3 screens with my hardware (and I don't have room for three 32" monitors anyway). The 12 GB gpu is the problem, probably.

             

 

 

 

 

I use a three Monitor setup for years now ( all in 4k ) and have no problems at all using MSFS2020. 

To say i use one Monitor for MSFS2020 and the others for LNM and other stuff and i have a superb performance and fluid with MSFS2020. 

So all good for me at this stage...

cheers 😉

Yeah but in your case you're not actually running a setup where MSFS is displaying on three 4k monitors. You're running MSFS on one monitor and some desktop apps on the others. 

I run MSFS 2020 across 3 48" 4K OLEDS and agree with @GSaldenthat each additional monitor will cut your frames more or less in half.

Thats what i say with that, not using all three monitors for MSFS but like this mine is fine !

And for your setup it is only logical that you have performance problems and that will never really work because the performance and the fluid always go down the drain, ( not even with future graphics cards ), not the next years i assume !!!

cheers 😉

After Mike cleared up why he did not have a performance drop of 40-50% with each extra outside view ( he uses a high end gpu for each outside view ) of you only have 1 gpu connected to 3 outside views you will experience lower performance.

In my case I am using just 1 extra outside view so my 4090 has a relaxed life.

My biggest performance hit is using PSXT live Traffic.  At Fly Tampa EHAM (Amsterdam) with 40 parked ac and 14 moving ac this hits performance. Then icw with bad weather my framerate drops to 37-39. 

But using Lossless Scaling I always see 60 FPS on both screens.

I recently tried with 3x 4K but then performance was 22-23 FPS ( without LL )
